Comments: Plant galls vary widely in appearance and causative agents, and except for some of the very colorful or common, are relatively little studied. This book is an extremely detailed treatment of the subject by an author with a lifelong interest. This book is not an identification guide, it is a scientific study of how they form, the insects or fungi that produce them, their evolution, etc. This may well be the most comprehensive treatment of the subject presently avaialble. If you need a field guide instead, you might consider Plant Galls of California and Other Western States. 562 pages.

Although its range is quite limited, this is a useful resource regardless of where you live. Descriptions are detailed and the photography is well done.
